Connection and Set-Up
The Reference 3.5's speaker binding posts accept bare wire ends, connecting pins,
"banana plugs" or "U"-shaped spade connectors.
Note: The dual sets of speaker connectors on the rear panel can easily be mistaken
for "bi-wire" binding posts, but they are not. Please read below for further
explanation.
The top two connectors are labeled "Speaker In" and provide a full-range connection to
the Reference 3.5. These are the terminals you will use to connect the output of your full-
range amplifier to the 3.5's.
The lower set of binding posts are labeled "Sub In" and are connected directly to the
Reference 3.5 woofer's secondary "auxiliary" voice coil. They are intended to work with
the optional Reference SA power amplifier to generate enhanced bass performance. The
SA amp operates independently from your main amplifier, extending the Reference 3.5's
deep bass performance down to the range typically associated with full-size subwoofers.
For more information about the remarkable Reference SA amplifier, please contact your
Anthony Gallo Acoustics dealer or us directly.
Note: Although it's possible to use another power amplifier with the "Sub In"
connection it's very important that you contact us for further information regarding
crossover settings, etc. There is the possibility of speaker damage if the proper
conditions and steps are not followed, and should such damage occur it will not be
covered under warranty.
Important Phasing Note: Start by connecting the positive and negative terminals
from your amplifier/receiver to the corresponding positive and negative terminals on
each speaker. However, once the system is fully broken in, we encourage you to
reverse the polarity by switching the red and black inputs on each speaker (note: this
must be done for every single speaker and your subwoofer will need to have its
phase reversed, or the entire system will not sound right). You may find that this
"absolute phase reversal" sounds better in your room, as we have found in many
cases it does.

Bases
The Reference 3.5 base is made of Garolite, a resin laminate that is dense and
inert. Using Garolite helps damp resonances that might otherwise adversely impact the
sound of the speaker. The somewhat mottled appearance of the material is normal and
should not be considered a cosmetic defect.
You will note that underneath the bases there is an area that contains a viscoelastic
substance. This gel material helps to decouple the Reference 3.5 from the floor. We have
found that using the gel is superior to typical spike systems, hence its presence here.
Note: Be careful to lift the speakers when moving them, as you can pull the gel
away from the base if you don't. If you are concerned about the gel material leaving
residue on your flooring, do not remove the protective plastic covering the gel on
the bottom of the base.
Getting Connected -- Hooking Up your Nucleus Reference 3.5 Speakers
Caution: Failure to turn off the receiver or amplifier before connecting your
speakers may result in damage to your system. You should always turn the
receiver or amplifier off before making or changing any connections.
